A ''Do Not Erase'' thingie maybe would have prevent it, but really, i dont think that anyone should whipe off a whiteboard full of writing without even knowing who wrote it or permission, that sucks for you, Op.

First. Make him re-write it....Then. Make a contract that he buys your breakfast lunch and dinner for the next 10 weeks. And has to be your slave for the next 10 days. Tell him 10 hours of my time is more than 10 weeks of yours..then call him an idiot and fire him....xD

So you spent 10 hours working on something but didn't do anything to preserve it? It was bound to happen.

ever heard of excel? or MS project? it's not 1972.

Oh god, you poor thing. You have my sympathies- how frustrating.

It's the conf room board, not yours. You had no reasonable expectation of monopolizing the board, esp. w/o telling the appropriate people. What would you had done if the boss walked in 8 hrs into your writing and said "I need the room to meet w/ someone in 10 mins. Please clear the board before you leave."?? The cleaning crew could have cleaned the board if your assistant didn't. How do you know it was your assistant? Another assumption?!?!? See the trend here?!? WFT good is a schedule on a white board?? I'm sure the supervisors would want something in a file or printed out.

Ergh. Like a few other people have said... Microsoft Project. The people that suggested "typing it" are retards and haven't heard of MS Project, probably just like you.

YDI for assuming a conference room board is yours and for relying on ink and plastic instead of a hard drive.

I had no idea time machines existed until now. You must be a caveman. How does it feel living in the twenty-first century? You must be in shock by all the handy new gadgets we have created, such as the COMPUTER. *gasp* Dumbass.

A simple text/email to your assistant could have prevented this...
